PIPE-HANGER.

SPECIFICATION forming part of Letters Patent No. 555,913, dated March 3, 1896.

Application filed February 11, 1895. Serial No. 537,854. (No model.)

This invention has for its object to provide a novel hanging device for use in supporting plumbers and steam-fitters pipes upon ceilings or walls of rooms or chambers. Hanging 1 devices for this purpose should be so constructed as to support a plurality of pipes, and in such manner as to permit the said pipes to be placed in position and removed singly independent of the others of the same group.

One part of my invention consists in a twopart pipe-hanging device, comprising a support and sustaining means intermediate its ends, a hanger and a holder independent of a and arranged on said support at one side its sustaining means and embracing and to sustain said hanger, substantially as will be described.

Other features of my invention will be here inafter described and particularly pointed out in the claims.

In the drawings, Figure 1, in elevation, partial section, shows one form of pipe-hanging device embodying my invention; Fig. 2, a vertical cross-section on the dotted line 00 00, Fig. 1; and Fig. 3 is a modification to be referred to.

Referring to the drawings, in the particular construction selected and there shown for illustration, (1 is a support of suflicient length to accommodate the desired number of pipes, and preferably semicylindrical in cross-sectional shape, as shown in Fig. 2, where it has a curved or cylinder surface 1 and a flat face 2. The support is herein shown as provided at its middle with a suitable boss or, from which projects a threaded screw or shank a by which to secure the support to the wall or ceiling.

The hangers Z) of desired number are shown as ring-like and adapted to be slipped upon the pipes, they being provided with suitable heads I) of a cross-sectional shape to fit and,

with the holder a, complete the cylinder, said heads b for this purpose having a curved surface 3 and a flat face 4:, which latter when the hanger is placed in position abuts against the flat face 2 of the support, as best shown in Fig. 2.

To bind the hangers to the support I have herein provided what I call holders 0, which embrace both the support and the hangers, the said holders, in the present instance, being ring-like in form and adapted to slide upon the support. As shown, the support is provided at its opposite ends with threaded nipples a upon which may be screwed nuts d to act lengthwise of the sup- 1 port to bind the hangers and their holders tightly together. For this purpose the hangers, near the ends of their heads, are provided with inclined surfaces b of preferably sharp inclination, so that when the adjacent hangers are pressed together lengthwise the support by the nuts d the holders 0 will be wedged upon these inclines and thereby tightly bind the hangers to the support.

In placing the pipes in position the hangers are first slipped upon the pipes, and the middle pipe first raised into position with its hanger in contact with the support, and the two rings at its opposite sides slipped over the ends of its head, thereby holding the middle hanger in position. The side pipes are next raised and the inner ends of their hangerheads inserted in the holders 0, which bind the middle hanger in position, and their outer ends are then held in similar manner by other holders slipped thereover, after which the entire series are bound together by means of the clamping-nutsd.

In Fig. 3, showing a modified form of my invention, and as shown adapted for a single pipe only, the support f is made semicircular in shape to embrace one half the pipe, its ends f being turned outwardly and provided with screw-threaded shanks. The hanger f is also substantially semicircular, embracing the other half of the pipe and having its ends f turned outwardly to abut against the ends f 'of the support f. The holders f are slipped over the outturned ends f f, emloracing the same, and are held in position by the nuts f screwed upon the threaded shanks. This embodies essentially the same invention as Figs. 1 and 2viz., a support, a hanger, and a holder engaging and embracing the same. My invention is not limited to the particular construction herein shown, for it is evident the same may be varied without departing from the spirt and scope of the invention.

I claim- 1. A pipe-hanging device comprisingasupport, a plurality of hangers arranged end to end thereon and provided respectively with oppositely-extended projections, and holders arranged on said support, the intermediate holders being arranged respectively between adjacent hangers and embracing projections on each, substantially as described.

2. A pipe-hanging device, comprising a support, one or more hangers arranged longitudinally thereof, sliding holders 011 the said support and engaging and thereby attaching said hangers to said support, and a clamp or clamps at the ends of said support to clamp the said holders in holding position, substantially as described.

V 3. A pipe-hanging device, consisting of a support, one or more hangers arranged lon-.

gitudinally thereof, holders engaging said support and hangers and serving to attach the latter to the former, and one or more clamps acting in the direction of the length of the support to clamp the said holders in position on said support, substantially as described.

4. A pipe-hanging device, consisting of a semicylindrical support having a flat face along one side, one or more hangers having semicylindrical heads with fiat faces to cooperate with the fiat face of said support, and one or more sliding ring-like holders on the support to embrace and hold the said hanger or hangers, substantially as described.-

5. A pipe-hanging device comprising a sup port, a plurality of hangers arranged thereon, projections on said hangers, and holders arranged on said support and passed around the projections of and thereby holding the said hangers, substantially as described.

6. A two-part pipe-hanging device, comprising sustaining means, a support extending at either side thereof, a hanger member arranged below said support and provided at either end with extensions arranged to cooperate with the extensions of said support, and holders arranged to co-operate with said support and embrace said hanger extensions to firmly clamp the same in locked position against said support, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
